WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 357.803, dated February15, 1887.

Application iilcd January 22, 1885. Serial No 153,678. (No model.)

.To all whom it may concern.-

Beit known that I, PETER WHITE, of St. Louis, Missouri, have made a newand useful Improvement in Tater-Closets, of which the following is afull, clear, and exact description.

The improvement relatesto what are termed tank7 water-closets; and itconsists in the means employed in effecting the gradual closing of thevalve which is used in discharging the water from the tank.

The annexed drawings, making part of this specification, illustrate theimprovement.

Figure l is a vertical section ltaken through the tank. Fig. 2 is a planof the tank. Fig. 3 is a View, upon an enlarged scale, showing thetank-valve partly in elevation and partly in section, the valve beingseated. Fig. 4 is a vertical section ofthe tank-valve, the valve beingunseated. Fig. 5 is a horizontal section on the line 5 5 of Fig. 3. Fig.6 is a horizon-V tal section on the line 6 of Fig. 3. Fig. 7 is ahorizontal section on the line 7 7 of Fig. 3. Fig. 8 is a horizontalsection on the line 8 8 of Fig. 3.

The same letters of reference denotethesame parts.

The water is let into the tank A through the supply-pipe a, and theintlow is regulated by a ballvalve, B, ofthe customary type. The outflowfrom the tank is controlled by means of the valve G, which is adapted tobe unseated by means of the lever D and chain E, Figs. l and 2. Thelever turns upon the fulcrum d and the chain leads from the lever D tothe closet trunk mechanism. (Not here shown.) ByV drawing the chaindownward the tank-valve C is raised from its seat c, Figs. 3, 4, and thewater iiows from the tank into the pipe G, which leads to thewater-closet bowl. (Not shown.)

The construction of the tank -val've C and ,the means therewithimmediately associated for controlling the closing of the tank-valvewill now be described.

Vithin the seat c, and somewhat smaller in diameter than the seat, so asto form a waterpassage, c', between the two parts, is a cham` ber, I,that is open at the upper end to admit the water of the tank. The valveG is provided with a plunger, C', having a cup-leather valve, C2, thatis turned downward and fitted to work in the chamber I. XVhen the valveO is unseated, as in Fig. 4, the water ilows from the tank A through theannular passage c',

and past the chamber' I into the pipe G, as indicated by the featheredarrows in Fig. 4.-

Water also flows past the cup-leather C2 into the chamber I beneath theplunger C. 'The stem C3 of the plunger C is made hollow, to admit atube, 0*, which projects upward from the bottom of the chamber and fitsloosely in the plunger-stem C, and with its other function serves as aguide on which said stem C3 moves. As the valve C closes to its seat thewater within the chamber I is forced thence, by reason of the plunger C'and cup-leather C2 descending within the chamber I, as represented inFig. 3,. upward around the tube Ct, and between the tube and theplunger-stem C3, and into the space C5 within the plunger-stein abovethe tube C. The water thence passes downward through the tube C* into achamber, C6, beneath the tube, and thence through the orifice CT intothe pipe G. As the valve C cannot seat until the water is mainly forced,in the manner described, from the chamber I, and as the passage from thechamber to the pipe G is a restricted one, substantially as shown, thevalve is necessarily seated gradually. The iiow from the orice C7 isgraduated by means of the adjustable plug C8. The valve C is chamberedout around the plungerstem C3, substantially as shown at C", Fig. 1I,and from the space C a passage, C10, leads upward through the stem C ot'the valve to the trap C. The water within the valve C can thus escapeupward through the valve, and thence back into the tank again.

I claim*- 1. The combination of the tank A, the seat c, the chamber I,the valve O, connected by tube C4 with the plunger C', said plungerbeing provided with the cup-leather C, the stem C, fitting loosely onthe guide-tube 0*, and the chamber C, having the orifice O7, providedwith the adjustable plug GB, substantially as described.

2. The combination ot the tank A, the seat c, the valve C, having thehollow stem C, the plunger C', having the cup-leather C2, the hollowstem C", the guide tube 0*, tting loosely in the said stein C",and thechamber C, having the orifice Ci, all constructed and operating asdescribed.

Witness my hand this 23d December, 1884.
